Does anyone here have to turn up the fans on their Mac when using flash?

Does anyone here have to turn up their fans on their Mac when using flash? Because I have to on my iMac and I used to have to on my MacBook as well... Does anyone else have this problem? If I don't turn up the CPU fan to cool it the computer starts lagging majority on everything then sometimes locks up...

I used to but then one of my fans broke, so I don't trust things like SMCfancontrol and what not. Rather it get hot instead of breaking for 5mins of cafeworld.

My iMac gets hot easy so I keep the HDD and CPU fans on at about half speed all the time I hope none of my fans break, though its an old machine so it wouldn't be as bad as if one of my MBP fans broke. I haven't had to use fan control on my MBP anyway

The fans in an Imac should be fine it doesn't move around as much as a portable IMO. lol I don't have an Imac though sadly

Also if the computer body hot to the touch is that a good sign? I mean that shows it's dissipating and not holding the heat in.
